SPECIFICATION forming partoof Letters Patent s a dated A g a 25, 1903. Application filed June 2, 1903. Serial No.159,789. (No model.)

To all whom it may concern:

Be it known that I, J OHN OARLsoN,a citizen of the United States, residing at New York city, (Brooklym) county of Kings, and State of New York, have inventedcertain new and useful Improvements in Split Gear-Wheels, of which the following is a specification.

This invention relates to a split gear-wheel which is so constructed that the rim-joint breaks line with the hub-joint and that the parts are so connected as to obtain a split gear-wheel having minimum parts and possessing superior strength.

In the accompanying drawings, Figure 1 is- I which contact at the diametrically opposite angles to the lines at. .provided with two integral diametricallylines I), such lines being arranged at right Each hub-section is The hub of the wheel is also ct, while each of the arms 12 will project over one of such joints. Each of the two adjoin ing arms b is connected to the common web (1, by a bolt 0, while each arm 11 is connected by a separate bolt 0 to each'of the two webs a Bolts 01 serve to connect directly the two adjoining'arms 19 near the hub.

It will be seen that by the construction described the two halves of the hub are solidly connected to one another by the two rim-sections and that in turn the two rim-sections are solidlyconnected to each other by the hub or that, in other Words, the hub-joint breaks line with the rim-joint. The result is that the sectional gear-wheel made according to my invention is composed of a minimum number of parts and is as strong for all practical purposes as a solid gear-wheel.

What I claim is- In a split gear-wheel, a pair of semicircular hub-sections having each three forked arms 'of-which two are arranged in alinement, combined with a pair of semicircular toothed rim-sections having a web which is straddled by the forked arms, bolts that connect the .forkedarms to the web of the rim-sections, land bolts that connect the adjoining arms of
